100 V Power Amplifiers
Order No. 17.3860
Digital mono PA power amplifier, with an
energy-saving effect.
• 1 x 250 W
RMS
• Class D concept with a high efficiency of
more than 90 % to reduce energy costs
• Additional integrated energy saving
functions, e.g. unit automatically goes to
standby mode when no input signal is
present (as soon as an input signal is
detected, the amplifier is automatically
switched on again)
• Requires a significantly lower recharge-
able battery capacity for emergency
power operation than 100 V analogue
amplifiers
• Clearly reduced cooling requirements due
to low heat dispersion
• Maintenance-free cooling and silent
operation due to fanless cooling concept,
thus especially suitable for noise-sensitive
areas, e.g. offices, conference rooms or
churches
• Special protective circuits prevent dam-
ages caused by short circuit or overheat-
ing
• Extensive, menu-controlled settings
• Switchable 200 Hz high-pass filter,
6 dB/oct.
• Additional priority input
• LCD for the operating parameters
• Mains operation or 24 V emergency
power operation
